Khan Academy: Physics: Average Velocity and Average Speed From Graphs

Physics fanatics time five cars as they pass on the highway. They use the times and a 20-yard distance to calculate velocity. They also graph distance vs. time. A page of student pre-lab questions is provided in addition to the activity...

Twelve pages of mostly multiple-choice questions comprise this comprehensive New York Regents physics exam. It covers an entire year's worth of physics curriculum and requires about three hours for completion. Review the questions to...

Give every type of learner in your physics class an opportunity to demonstrate what they have learned throughout the year. From analyzing tables and graphs, to evaluating diagrams and solving problems, there is an outstanding variety of...

The presentation includes nine time vs. position graphs. The first three are meant to be used for teaching how to read them. The next three provide an opportunity for students to practice reading them, while the last three display the...

Video lecture provides an example of calculating speed and velocity. [11:46]

Ever wonder what happens to light when it gets in its own way? Observe Thomas Young's double slit experiment and what we learn about the properties of light from studying it. Also describes other light experiments that could be done to...

Find out how to use the PV loop to draw the Ea (Arterial Elastance) line, and what it represents. Rishi is a pediatric infectious disease physician and works at Khan Academy. [11:21]

Take a look at an organized physics course. The 34-section electronic textbook covers material in AP® Physics 1 and 2. Teachers use the text to supplement lectures and have the class work through the labs. Each section contains...

How to analyze graphs that relate velocity and time to acceleration and displacement.

Velocity or speed? Instantaneous or average? Keep building your physics vocabulary.
